TRANSOM TRUNNION MECHANISM.

Application filed November 9,

To all whom it may concern:

Be it known that I, GEORGE 0. SMITH, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Transom Trunnion Mechanism; and I do hereby declare the :following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper tains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to transom trunnion mechanism, and. particularly to improvements therein whereby the trunnion can be withdrawn from the transom frame and the transom removed when desired. To accomplish this I make the trunnion mechanism in the form of a spring actuated bolt or trunnion provided with an arm, and under this arm I provide a lever for withdrawing the bolt or trunnion, in the axis of which I make an opening adapted to receive the point of a screw-driver or other suitable tool, by the rotating of which the trunnion is raised out of its socket in the transom frame.

The features of my invention are hereinafter fully set forth and described and illustrated in the accompanyin g drawings in which Figure 1 shows a view in elevation of a transom frame with a transom therein. fitted with my improved trunnion. Fig 2 is an enlarged view of my improved transom trunnion with sections of the'transom and frame, with parts broken away in section. Fig. 3 is a view in elevation of the rear side of my improved transom trunnion.

In these drawings A is a transom-frame, and B a transom operating therein. For supporting the transom B in place, trunnion sockets C (shown in dotted lines) are provided in the trunnionframe A, in which trunnions constructed as follows operate.

As illustrated in. Figs. 2 & 3 the trunnion-frame is shown as consisting substantially of a face-plate D having lugs (I (Z projecting from the inside face thereof, between one of the ends of which I provide a circular trunnionsocket (l which extends through the face-plate D. In the opposite ends of the lugs (Z (Z from the socket (l, I make a transverse circular opening (1 in which I pivot the journals 0 of a lever E, which lever E normally rests nst the back of the face-plate I), and is capable of being raised up between the lugs (Z (l, and in the journals 0 thereof I make an opening e, preferably triangular, adaptcd to receive a screw-driver or other suitable tool inserted through an opening in the transom B. In the circular socket d I place a bolt or trunnion F so Specification of Letters Patent.

that it will slide freely therein, and extend through the faceplate D as clearl'yshown in Fig. 2. On the inner end of the bolt or trunnion F there is an arm f which extends backward between. the lugs (Z d over the end of the lever E and normally resting thereon, and thereby limiting the projection of the bolt F through the faceplate D, and on the rear of the face-plate D, I secure a spring G which rests upon the inner end of the bolt or trunnion F retaining it in the normal position shown in Figs. 1 a 2.

In securing this structure to a transom or window, a mortise II is made therein in which the face-plate D is secured, in the usual manner.

In operation, to remove the transom 13 from its frame A it is only necessary to insert a screwdriver or other suitable tool through the opening b into the opening a and rotate it which raises the lever E operating against the arm f of the bolt or trunnion F, and withdraws the trunnion from the trunnion-socket in the frame A, the spring G- automatically re turning the parts to their normal position, and retaining them in such position when the transom is in place in the frame. It will be observed that the opening b is only made in the inside of the transom so that when in place it is impossible to remove the transom from the outside.

While I have herein shown and described my invention as a transom-trunnion, it is obvious that it is equally applicable to pivoted window-sash, and also as a sash look when desired, without any change of construction.

Having described my invention so as to enable others to construct and use the same, what I claim is:

1. The combination in a trill)SOIIldil'lllllliOll, of a frame, a bolt or trunnion sliding in said frame, an arm 011 said bolt or trunnion, a lever pivoted in said frame, adapted to engage the arm on said trunnion or bolt, and a spring on said frame engaging. said bolt or trunnion, substantially as set forth.

2. The combination of a transom-frame having a trunnion-socket therein, a transom having an opening in one side thereotfa frame secured in the edge of the transom, a trunnion or bolt sliding in said frame and adapted to enter the socket in the transom-frame, an arm on said trunnion or bolt, a lever engaging said arm, journals on said lever having an opening therein mounted on said frame so that. the opening in said journals will coincide with the opening in said transom, and a spring in said frame engaging the bolt or trunnion, substantially as set forth.

In testimony whereof I nfiix my signature, in presence of two witnesses.

GEORGE 0. SMITH.

It is hereby certified that the name of the assignee in Letters Patent No. 864,759, granted August 27, 1907, upon the application of George 0. Smith, of Erie, Pennsylvania, for an improvement in Transom Trunnion Mechanism, was erroneously written and printed Forest G. Piper, whereas said name should have been written and printed Forest 0. Piper; and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the case in the Patent Otfice. I
